Help
1

i’m beginner to nix so i’m not that useful to tell what might be causing this, it worked a while a go and without any updates it stopped working

{ ... }:
{
  systemd.user.services = {
    pipewire = {
      enable = true;
      wantedBy = [ "default.target" ];
    };
    "pipewire-pulse" = {
      enable = true;
      wantedBy = [ "default.target" ];
    };

    wireplumber = {
      enable = true;
      wantedBy = [ "default.target" ];
    };

  };

  hardware.bluetooth.enable = true;
  # Enable sound with pipewire.

    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    jack.enable = true;
    # use the example session manager (no others are packaged yet so this is enabled by default,
    # no need to redefine it in your config for now)

You shouldn’t actually need those since pipewire uses socket activation by default.
This also applies to pipewire-pulse, meaning that systemd is already binding on those sockets on behalf of the daemons.
And since you are automatically starting them by themselves without getting triggered by the socket unit you are seeing this conflict:

I’m not 100% sure, but I think removing the systemd.user.services section should fix your issues (Edit: or at least part of them).
As to why this is only happening now, I don’t know.

3

Also media-session has been deprecated (but I think that already happened last release?), and has been replaced with wireplumber, which is automatically enabled if you enable pipewire.

4

sorry for the late reply i forgot to check my post, adding these lines don’t affect the sound in anyways, i’ve added after i had this issue since but they didn’t work so i just left them there, but since you mentioned it i’ve removed them but the issue still persist

5

I’ve tried manually and it still doesn’t work, why is pipewire is not working properly as it was?

6

How exactly did you try, and what was the output?

Did you stop the following units before trying (using systemctl --user stop $unit1 $unit2 ...)?

  • pipewire.service
  • pipewire.socket
  • pipewire-pulse.service
  • pipewire-pulse.socket
  • pulseaudio.service (just to be safe)
  • pulseaudio.socket (just to be safe)
  • wireplumber.service

Did you then run the following commands (in order, but having them run simultaneously)?

  • pipewire
  • pipewire-pulse
  • wireplumber

What does lsof /dev/snd/* print?

Did it still contain about /run/user/1000/pulse/native being already in use, or did the error change?
If any of the commands exited on their own, what did they print?

If the commands all keep running (which is good), does running pulsemixer and/or alsamixer (packages pulsemixer and alsa-utils respectively) work (as in, does it show a single volume control)? In the case of alsamixer does showing the sound card for your actual hardware (F6) show that the volume sliders are non-zero and unmuted?
What does pw-link --output show?

7

nope i didn’t stop these services manually at all

yes the order is important pipewire first then pipewire-pulse then wireplumber

lsof /dev/snd/*

pw-link --output

Maybe it’s not relevant, sometime when my system produces no sound, just run systemctl --user restart pipewire and the sound will come back again.
This is my working config in my audio.nix, hope it can help:

{lib, ...}: {
  # rtkit is optional but recommended
  security.rtkit.enable = true;
  services.pipewire = {
    enable = true;
    alsa.enable = true;
    alsa.support32Bit = true;
    pulse.enable = true;
    # If you want to use JACK applications, uncomment this
    #jack.enable = true;
  };
  services.pulseaudio.enable = lib.mkForce false;
}

see i’ve tried all systemd commands, it’s like pipewire literally not installed;

 systemctl --user restart pipewire
Failed to restart pipewire.service: Unit pipewire.service not found.

I’ve had some weird audio issues before, and using qpwgraph was instrumental in troubleshooting them.

please read this post if you have the same issue as mine, he shows the solution there:

solution from this guy ( worked for me ):
delete all unused symlinks under this path:

ls -l ~/.config/systemd/user/

everything even those inside default.target.wants and socket.target.wants
